Fast growth of population and energy crisis are the main issues of today world. The objective of present study was to use renewable energy resources for sustainable environment. The biogas was produced from fruit and vegetable waste by anaerobic digestion and application of its byproduct as a fertilizer. The fruit waste, vegetable waste, buffalo dung was analyzed for moisture content, ash, protein, fiber, fat, carbon to nitrogen ratio, COD and BOD. Temperature and pH was checked after regular interval of time. Proximate analysis of Digestate(organic residue left after biogas production) was done. Overall pH was almost neutral except fruit waste which had slightly acidic pH. The highest biogas was produced from vegetable waste followed by the mixture of fruit and vegetable waste and fruit waste in decreasing order. Compost was made by using the waste generated by university. Vegetation was grown to see the effect of compost, digestate and chemical fertilizer on them.
